Title: Single cell observation of bacterial gene expression during mollusc infection by a marine pathogen
Microbial-host relationship is composed of a multitude of interactions occurring at the microscopic scale. Recent fluorescence microscopy approaches shed new light on the bacterial life style during infection, where division of labour triggers phenotypic heterogeneity, each subpopulation performing a different task to optimize colonization of the host. However, these observations are rare, and mostly confined within mammal pathogens. The aim of this study will be to fill the gap, exploring for the first time the expression of virulence genes of a marine pathogen of mollusc at the single cell level.
Specifically, a strain of Vibrio harveyi infecting the abalone Haliotis tubercultata will be genetically modified to contain a reporter gene, allowing the expression of specific genes to be followed by fluorescence microscopy. The student will develop a protocol to construct such bioreporters, using mini-transposons or replicative plasmids. Bioreporters will be tested in vitro, ex vivo using haemocyte primocultures and then in vivo during abalone infection, and bacteria will be observed by epifluorescence microscopy. The student will also explore the expression of virulence gene during micro-habitat colonisation (gill, heart and foot tissues, haemolymph…).
This project combines microbiology, molecular biology and microscopy, and will help better understanding the principles driving the virulence of marine pathogens.
Necessary skills: Strong microbiology knowledge
Desirable knowledge: molecular biology, microscopy
Minimal duration of the internship: 5 months
Further readings:

RESEARCH PLACEMENT ASSISTED BY ESMB
ESMB shall announce that the society is launching an initiative to help Masters/MSc and PhD students to find Marine Biotechnology related Research and Work placements within Europe. Such placements, if planned for a minimum duration of three months, can be supported by Erasmus grants.
A "Research Placement page" is open on our website, now running for the academic year: 2017 - 2018.
If you are willing to host student(s) during 2017-2018 to work in your lab, your company, along side your post-docs, R&D employees, etc. please send us the following information
- your name and institution address
- title of a potential project/activity
- key pre-requisites
- duration (with approximate dates)
If you are a student interested to participate to the scheme, please send us the following information
- your name and university course
- expected placement : duration (with approximate dates) & topic
- cover letter and reference letter (embed in submission form)
Please forward all information by contacting Claire.Hellio@univ-brest.fr, more info here
